As far as I can see, the only unexplained acronym is "SoC". The first result on Google for that term is the wikipedia article explaining "System on a Chip". HN has always been for technical news. There is always some domain specific knowledge required in technical topics. Judging by the comments here though, it's obvious that the domain specific knowledge this article assumes (which isn't particularly great - not much more than a rudimental understanding of the components that make up a computer) overlaps with quite a number of HN readers. If you read an article that you don't understand, use it as a learning opportunity. The resources are at your fingertips!
